Flat Belt Treadmill-like Rotation Toothbrush

摘要

In an embodiment of the disclosed technology, a toothbrush head formed of a bristled tread is rotatable about at least one vertically disposed sprocket. The toothbrush head has an elongated neck with sprockets extending axially therefrom. Bristles are wrapped around either or both sprockets. The bristles may be on a single belt wrapped around both sprockets. Alternatively, the bristles may extend from two spindles, each fitted around a sprocket. The sprockets rotate circumferentially within an upper head portion of the device. The bristles spin 360 degrees (full rotation) around the sprockets and within the stationary head. The head portion itself is replaceable or changeable, such that a handle portion may be used by multiple users or replaced.

主权项

1. A toothbrush comprising:
a housing having an upper head portion and a lower neck portion; two spaced-apart drive sprockets extending through said upper head portion substantially parallel to said lower neck portion; and a continuous, rotatable belt with tread on an interior side thereof, simultaneously wrapped around each of said two spaced-apart drive sprockets, each said drive sprocket having a plurality of flanges extending out therefrom, such that at least one flange of each said drive sprockets is constantly engaged with said tread when said tread is rotated by rotation of said two spaced-apart drive sprockets; wherein said two spaced apart drive sprockets are housed within said upper head portion of said housing; and a plurality of bristles extend outward from said belt.
